RECORDING DEVICE.

Application iiled September 28, 1912.

To all ywhom t may concern Bc it known that we, lVILMnR 1V. SALMON and FRANK L. DoDGsoN, citizens of the United States, and residents of the city of Rochester, in the county of Monroe and State of New York, have invented a new and useful Recording Device, of. which the following is a specification.

This invention relates to railway signaling.

Modern systems of fixed signaling are often criticized, because they almost invariably fail to provide a means, whereby a train improperly entering a signal section is stopped irrespective of any voluntary action by the engine runner.

The primary object of this invention is to provide a means, whereby a record will be automatically made of the passage of a train into an occupied signal section, of such a character, that at any future time it may readily be determined at what particular time the signal section was vthus entered.

The advantage of the invention resides in the fact, that engine runners knowing a permanent and indisputable record will be made if they allow their train to enter an occupied signal section, will be extremely careful not to do so. This cxtreme precaution on the part of engine runners will undoubtedly result in very materially decreasing the number of collisions now due to the entrance to an occupied section of a second train.

@ther objects and advantages will appear as the description of the invention progresscs, and the novel features of the invention will be particularly pointed out in the appended claims. V

In describing the invention in detail, reference is had to the accompanying drawin wherein we have illustrated a preferred phy a al embodiment of our invention. and wherein like characters of reference designate corresponding parts throughout the several views, and in which- Figure 1 is a schematic illustration of a preferred physical embodiment of our invention; Fig. 2, is a schematic illustration of another embodiment; Fie'. 3, is a schematic illustration of a modification of the embodiment of Fig. 1; Fig. il, is a schematic illustration of a modification of the embodiment of Fig. 2.

Referring to Fig.:1, 1- and-f2 designate the Specification of Letters Patent.

Serial No. 722,812.

two rails of a railway track having the ordinary and well known insulating joints, as 3, inserted in both rails at intervals, forming what is known as the ordinary and well known block, the entrance to which, by trains, is governed by the fixed signal l. The insulating joint 5, inserted in the rail 2, divides the block into two track circuit sections, designated by A and A1. A difference of potential is created between the rails of section A by means of the source of current G, and a difference of potential is created between the rails of section A1 by means of the source of current 7. Section A1 controls the ordinary and well known track relay 8, the terminals of which, 9 and 10, are connected to each track rail, 1 and 2. Thel armature 11 of relay 8 is included in the circuit of relay 12, which circuit also `includes the rail 2 between the insulating L joints 5 and 3 at the right hand end of section A, the battery 6, the rail 1 between insulating joints 3 in rail 1 at either' end of the block, the lead 13 which also serves to connect relay 8 with rail 1, the conductor 141 and conductor 15. This arrangement as is well understood by those skilled in the art, causes a deilnergization of both relays S and 12 by the presence of a train upon section A1 and a denergization of relay 12 only by the presence of a train upon section A.

The armature 16 of relay 12 controls the iiXed signal Ll, the circuit of which is as follows: one terminal of battery 17, conductor 18, armature 16, conductor 19, mechanism of fixed signal 4l, conductor 20 and conductor 21 to the other terminal of the source of current 17. As is obvious and is well understood by those skilled in the art, the fixed signal -f is moved to and held in the full clear position as shown, when the armature 16 is in its upper position as shown. Then a train passes the insulating joint 3 at the left hand end of section A1, the relay 8 is shunted, consequently the armature 11 drops, thus breaking the circuit of relay 12 and allowing the armature 16 to fall, thereby break-ing the circuit of the fixed signal l and allowing it to fall to the danger position. When the train Y leo las

in the lower position all of the time while any part of a train is upon the rails of the track between the insulating joints at either end of section A, and, consequently the fixed signal 4 remains in the danger position. vWhen signal 4 moves to the danger position it causes circuit controller arm 21 to move in contact with the contact 22. If another train enters section A1 while a preceding train is upon the section A, the fixed signal 4 necessarily being under Such conditions in danger position and the circuit controller arm 21 making contact with contact 22, then as following train will denergize relay 8, its armature 23 will -fall and in falling will make contact with member 24, thus completing the following circuit; one terminal of the source of current 17, conductor 18, armature 16, conductors 25 and 26, contact 22, circuit controller arm 21, conductor 27, armature 23, member 24, conductors 23 and 29, recording device 30, and conductors 31 and 21 to the other terminal of the source of current 17. Current flowing in the above traced path will cause an actuation of recording device 3() which may be of any well known type, by which a record of the exact time at which it was actuated will be permanently made. Regardless of the exact type of' recording mechanism 30 that may be used there will in all cases be a means such as member 32 operated simultaneously or by the mechanism of recording device 30, pivoted at 33 for the purpose of giving an indication, external to recording mechanism 30, that the same has been actuated. 1n the present case the pivoted member 32 is connected with a. link 34, which at its upper end carries a catch 35 which normally engages with an arm 36 attached to a disk 37 which cairies a weight 38, which normally lies in the upper position as shown. /Vhen the pivoted member 32 is actuated by an electrical e'nergiation of recording device 30, the link 34 will be drawn downwardly and the projection 39 rigidly attached to said link will contact with the fixed projection 40 attached to the side of recording device 30, and cause link 34 to be moved outwardly. so that catch 35 disengages arm 36 and allows disk 37 to be moved to another position by virtue of weight 38 tending to lower the center of gravity of the disk 37. The link 34 and catch 25 are normally held in engagement with arm 36 by means of spring 41 which exerts a constant tension upon link 34.

In practice the recording device 30 would ordinarily be placed in the same case with the mechanism for operating the fixed signal `4, so that by means of the external indicating mechanism above described it may immediately be determined whether or not any train has improperly passed fixed signal 4, since the last inspection, by merely opening .the door ofthe case inclosing the mechanism for controlling fixed signal 4, and glancing at the recording mechanism 30. 1f the recording mechanism 30 has been actuated, it will be shown by the position of disk 37 and an internal inspection of recording device 30 will show the exact time or times at which it was actuated, which will be noted,

then the disk 37 will be manually returnedto its normal position, as shown in Fig. 1.

The armature 23 of' relay 8 is so constructed and pivoted that whenit falls it will first contact withmember 24 and then pass beyond it out of contact with it and the member 24 has an insulating member 42 ated every time a train entered'upon section A1 and passed onto section A, because the entrance of the train upon A1 would cause signal 4 to move to the danger position and at the instant of its passage onto section A, the relay 8 being denergized, and signal 4in the danger position and relay 12 de'e'nergized, a circuit would be formed through the recording device. The ycontact of armature 23 with member 24 when it moved upwardly when a train passed out of section A at the Vright hand end would also cause an actuation of recording mechanism 30 if the insulating member 42 were not attached to the underside of member 24, because when a train passes from the right hand end of section A the signal 4 is in the danger position, the circuit controller arm is in contact with contact 22 and the armature 16 is making contact with conductor 25, so that all parts are in condition to complete a circuit through the recording device if armature 23 makes contact with member 24.

Although ordinarily a fixed signal when in the danger' position should not be passed by a train, there are times especially in the case of automatic electric block signaling where under proper precautions it is proper to pass a signal when in the danger position. Some means must, therefore, be provided, wherebyan engine runner may indicate that although the signal was in the danger position, he passed it knowingly. Such a means in applicants invention is provided in the push button 43. If the fixed signal 4 is in the danger position, so that a record will be made if a train passes into section A1, then if the engine runner actually desires to enter the section, he mayl assume'the' responsibility, but indicate" his knowledge by depressing the push button 48. The `depression of push button 43 connects ccnductors 44 and 45 so that a circuit is formed as follows: terminal of the source of current 17, conductor 18, armature 16, conductors 25 and 44, push button 43, conductors 45 and 29, recording device 30, and conductors 31 and 21 to the other terminal of the source of current 17. Current iiowing in the above traced path will cause an actuation of recording device 30, so that the exact time will be recorded at which push button 43 was depressed. The engine runner will then immediately cause his train to move upon the section A1, which will cause another actuation of recording device 30 and an eXact indication of the time at which the train entered the section. A later inspection of the record made by device 30 will then show, that the signal 4 was passed by an engine runner with full knowledge of the condition and with an entire assumption ofthe responsibilities b v him.

All parts in Fig. 2 similar to parts shown in Fig. 1 are designated by the same numerals.

1n the modification shown by F ig.`2 the entrance of a train upon. section A1 will cause signal 4 to move to the danger position, just as in the embodiment shown by Fig. 1 and a further movement of the train onto section A will result in the energization of stick relay 46. This is accomplished as follows: Upon the entrance of the train to section. A]L the relay 8 is denergized in the well known manner, which causes a deenergization of relay 12 thus allowing armature 16 to fall, thus breaking the circuit for signal 4 and allowing it to fall to the danger position, causing circuit controller arm 21 to make contact with contact 22, and

as armature 47 is allowed toV fall b v the deenergizati on of relay 12, as soon as the train has passed entirely from section A1 to section A, the following circuit will be formed: one terminal of the source of current 17, conductors 48 and 49, circuit controller arm 21, contact 22, conductor 50, armature 51, conductor 52, armature 47, conductor 53,

. stick relay 46 and conductors 54, 55 and 56 to the other terminal of the source of current 17. It will be noted that the above traced circuit cannot be formed until all of the train has passed beyond section A1 for until such is the case, the armature 51 will not be inthe upper position, but when the armature 51 is in the upper position and the circuit above traced is completed, the

`current flowing therein will cause the stick relay 46 to be energized, thereby causing armatures 57 and 58 to be raised to the upper position. After relay 46 has been ener gized by the circuit heretofore described, it is kept in the energized condition by reason of a current iiowing in the following circuit: one terminal of the source of current 17, conductors 48, 60 and 69, armature 57, conductor 70, Varmature 47, conductor 53, stick relay 46 and conductors 54, 55 and 56 to the other terminal of the source of current 17. 'l`his circuit remains completed as long as armature 47 is in the lower position which continues as long as relay 12 is deenergized, and as has heretofore been pointed out relay 12 remains denergized as long as a train remains upon the rails of section A, so that the relay 46 will remain enen gized until the tra-in which has accepted signal 4 has passed beyond the insulating joints at the right of section A. When a train is upon section A and the armatures 57 and 58 are in the upper position due to an enerfrization of relay 46, then the entrance of a second train upon the section A1 will. cause the relay 8 to be denergized, thereby causing armature 59 to fall and completing a circuit as follows: one terminal of the source of current 17, conductors 48, 60 and 61, recording device 30, conductor 62, armature 59, conductors 63 and 64, armature 58, and conductors 65, 55, and 56 to the other terminal of the source of current. Current flowing in the above traced path. will cause an energization of recording device 80, recording the exact time of actuation and a release of indicating member 37. If an engine runner finds signal 4in the danger position, but still wishes to enter the section A1, he may indicate his assumption of responsibility by depressing the push button 43, whereupon a circuit will be formed as follows: one terminal of the source of current 17, conductors 48, 60 and 61, recording device 30, conductors 66 and 67, push button 43, conductors 68 and 64. armature 58V and conductors 65, 55 and 56 to the other terminal of the source of current 17. The depression of the push button 43 by the engine runner and his subsequent entrance into the section A1 indicate the same facts that were discussed in connection with the description of the embodiment shown by Fig. 1.

Fig. Billustrates a modilication of the e, bodiment of applicants invention shown Vby Fig. 1. ln this figure the invention is shown as embodied in an apparatus not including1 the circuit controller 21 of Fig. 1. All of the parts shown in this ligure similar to those shown in Fig. 1 have been designated bv like characters of reference. The energizing circuit for recording device 30 is as follows: One terminal of the source of current 17, conductor 18, armature 16, conductors 25 and 27, armature 23, member 24, conductors 28 and 29, recording device 30a and conductor 31 to the other terminal of the source of current 17. he operation and circuits of the remainder of the figure are the same as those shown and described in connection with Fig. 1 and further explanation 1s therefore unnecessary.

The device shoivn by Fig. d is a modification of the embodiment illustrated by armature 59, conductors G3 and 6ft, armature 5S, and conductors and 65, to the other terminal ot the source ot current. The pick up circuit for relay d6, is as tolloivs: one

terminal of the source of current 1T, conductors 71, Txand 74, armature 51, conductor armature 16, conductor 53, stick relay 116, and conductors 54 and 55 to the other `terminal 0'1": the source oit current. The remaining` circuits together with the devices associated therewith are the same as thel embodiment shown by Fig. 2 and operate similarly so that further explanation is not required.

i-rpplicants have not herein described any particular torni ot' mechanism for that device designated by numeral 30, because the form of mechanism designated by 30 is immaterial to the substance ot applicants invention because applicants invention con templates the use of any iormot recording or registering mechanism which upon actuation will make or exhibit a permanent record of' the tact and the exact time of its actuation, andl applicants vish it to be distinctlyV understood that they consider any Vsuch form of mechansin to be designated and indicated by means ot numeral 80.

Although applicants have herein shown and describedrtheir novel recording device in connection With an automatically operated signal, it is to be clearly understood that its use is not so limited. The essential feature of the applicants invention issuch that it may be used as Well in connection with the manually operated as with the automatically operated signal, in 'fact it is necessary merely to employ track circuit sections and relays controlledv thereby, arranged according` to the principle of applicants invention, in order to enable applicants recording device to perform its function irrespective of any signal.

Although applicants have particularly described the construction of preferred physical embodiments of their invention, and have explained they operation and principle thereof, nevertheless, they desire to have it understood that the forms selected are merely illustrative, but do not exhaust the possible Vphysical embodiments 'of their idea of means underlying their invention.
